Abstract
The utility model discloses a shaft balancing jig, comprising two groups of a 4-connecting-rod mechanism and four hinge shafts (3, 5, 7, 10) used to fasten the connecting rods, a suspension ring (8), a lifting claw (1) and a locking rod (9) used to set the opening width of the lifting claw. The suspension ring (8) is fixed on the upper hinge shaft; the lifting claw (1) is arranged at the lower end of the lower connecting rod (4) of the connecting-rod mechanism; a location notch (11) is arranged on the locking rod (9), the opening width of the lifting claw can be fixed when the location notch clamps on the other middle hinge shaft. The utility model is simple in structure, safe and reliable, capable to improve production efficiency, easy to be moved and operated, and applicable to hoisting the shafts of railway freight cars.
Description
Technical field
The utility model relates to a kind of suspender that is used to lift axial workpiece.
Background technology
In axletree handling process, regular meeting runs into outstanding problems such as the axletree handling is cumbersome, and suspender is multifarious, and the suspender durability is poor, and has potential safety hazard, and work efficiency is low at present.
Summary of the invention
The purpose of this utility model provides a kind of axle class balance sling that is suitable for the lorry axle lifting, has steady, safe and reliable, the easy to operate advantage of lifting.
The utility model be achieved in that it by four hinge axis, suspension ring of two groups of four-bar linkages and stationary links, hang pawl and be used for locating and hang the dehisce locking rod of width of pawl and form, suspension ring are fixed on the upper hinge axle, hang pawl and be located at the lower link lower end of connecting rod mechanism, locking rod one end hinge is on a middle hinge axle, locking rod is provided with positioning groove, the width of dehiscing that hangs pawl can be fixed when positioning groove is stuck on another root middle hinge axle.
Earlier this suspender is positioned axletree central authorities during use, hangs the pawl location of dehiscing, suspender is descended to making hang the axle body bottom that pawl drops to axletree, upwards promote again to lock bar and lifting, hang the inside contraction clip clamping of workpieces of pawl with locking pole pair.
In order to prevent to hang the pawl axletree that in hoisting process, weares and teares, hanging pawl and the axletree contact site is provided with copper protective cover, this protective cover can be the type of electroplating usually or be welded.
The utility model adopts connecting rod mechanism to clamp axletree, and is simple in structure, safe and reliable, can improve the production work efficiency, and suspender moves very conveniently, simple to operate, is applicable to the lifting of railway truck axle class.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 left view.
The specific embodiment
As depicted in figs. 1 and 2, it is by four hinge axis of two groups of symmetrically arranged four-bar linkages and stationary links, suspension ring 8, hang pawl 1 and be used for locating and hang the dehisce locking rod 9 of width of pawl and form, four hinge axis are respectively upper hinge axle 7, a following hinge axis 3 and a left side, right middle hinge axle 5,10, suspension ring 8 are fixed on the upper hinge axle 7, hang pawl 1 and be located at lower link 4 lower ends of connecting rod mechanism, locking rod 9 left end hinges are on left middle hinge axle 5, lower end, locking rod 9 right side is provided with positioning groove 11, the width of dehiscing that hangs pawl can be fixed when positioning groove 11 is stuck on the right middle hinge axle 10.Hang pawl 1 and be provided with copper protective cover with axletree 2 contacts site, this protective cover can be to electroplate usually or welding fabrication.
Earlier this suspender is positioned axletree 2 central authorities during use, positioning groove on the locking rod 9 11 is stuck on the right hinge axis 10, dehisces to locate, suspender is descended to making hang the axle body bottom that pawl 1 drops to axletree 2 hanging pawl 1, upwards promote again to lock bar 9 and lifting, hang pawl and inwardly shrink clamping axletree 2.
